A friend told me that the first thing she replaced when her house burned down was the food sealer. So when they went on sale on QVC I ordered it. I really like it. But I did find that I can only do three packages at a time before it has to rest. I almost sent it back, I called the Mfg and was told since I did not order the top of the line that was just the way the machine is. It could seal but it would not suck out all the air after that. It's not a big issue for me because I don't buy that big in bulk anymore. Also, with mine, you have to slide the bag into the machine instead of setting it in and closing the lid. I would have preferred the other but it wasn't available when I got mine.
I got my daughters the hand held model with the quart size bags so they can keep their cold cuts and cheese longer.
